Abstract
Abstract A fuel supply control system for an internal combustion engine is disclosed. The system comprises a means connecting to an air control apparatus, regulating flow of air into the engine, at least one chamber in fluid communication with the cylinders of the engine fuel delivery means, the fuel delivery means terminating in an aperture such that said fuel, when forced through said aperture forms a continuous stream.
